SPECIFICATION forming part of Letters Patent No. 313,994, dated March17, 1885. Application filed June 1, 1884. (SpecimensJ Patented inEngland October 9, 1880, No. 4,103, and February 23, 1884, No. 3,817.

To all whom it may concern.-

Be it known that I, JAMES CROSSLEY, a subject of the Queen of GreatBritain and Ireland, residing at Bury, in the county of Laucaster,England, have invented certain new and useful Improvements inPaper-Makers Cotton Drying-Felts, Printers Machine-Blankets, and otherMachinery Cloths; and I do hereby declare the following to be a full,clear, andexact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

fabric.

The object of this invention is the manufacture of a cotton drying-feltfor covering pa- ;per-makers rollers or cylinders which shall he as evenat the joint (where the two ends of the fabric are joined together) asat the other part of the surface, and thus present no obstacle to thepaper or pulp in passing over the same; and my invention consists inweaving the parts of which the joining is composed half the thickness ofthe other part, or opposite sides of the fabric, so that when the twohalf-thicknesses are laid together one over the other and the warp endsare spliced by quilting or sewing together therewith the twohalf-thicknesses so laid together, a flush and even joining is obtained,the joint being exactly equal in thickness to the other part of thefelt.

In producing the fabric I employ an ordinary loom containing twelveheddles.

To start a piece of fabric, I commence to weave with half the number ofheddles-say those at the back of the loom, corresponding with what maybe termed the face of the This is continued until six inches (more orless) of the fabric have been woven of the half-thickness so produced. Ithen operate all the heddles, and so produce the full thickness of thematerial until the required length is produced. I then stop off theother half of the heddles-say those at the front of the loom,corresponding with the face of the fabric-and weave another six inches(more or less) of half-thickness; and in taking the piece from the looma short length of unwoven warp-threads is left attached at each end ofthe piece. The half-thickness ends are now laid together and securelyunited in the act of stitching in the protruding warp-threads, asaforesaid.

In accordance with this invention a joining is effected without tyingthe warp ends together, and which dispenses with all knots and otherprojections.

It will be apparent that this invention is equally applicable to seamingtogether the ends of printers machine-blankets and other endlessmachinery cloths.

I claim as my in vention- An improved endless felt blanket or machinerycloth of uniform thickness, composed of a piece of woven fabric havingoverlapping ends each of half-thickness, the outer sides of which formcontinuations of the respective sides of the fabric, while their innersides come together at mid-thickness of the fabric, and are united bymeans of the stitched-in warp ends, substantially as herein specified.

In testimony whereof I afiix my signature in presence of two witnesses.

JAMES OROSSLEY.
